Geometric confinement of chiral multilayer thin films also dictates the ambient stability and evolution of skyrmions. We observed the zero field (ZF) stability of [Ir/Fe/Co/Pt]\(_{20}\)  skyrmions over a critical range of geometric sizes (200 – 300 nm) (Section3b). [1]} While the chiral stripe phase dominates at large dot sizes, skyrmions are favoured for small dot sizes due to a reduction in magnetostatic energy. The ZF skyrmion size can be modulated systematically by a factor of 4, down to 50 nm, by varying geometric size and magnetic interactions. Such geometric tuning, enabling their small size and ZF stability, allows for the design of compact devices compatible with existing electrical architectures.
